After being ousted from his kingship in Leinster, and seeking help from King Henry II of England, Dermot MacMurrough enlisted the assistance of Richard fitz Gilbert de Clare, would-be earl of Pembroke (Wales), and a group of Cambro-Norman barons including the half-brothers Maurice FitzGerald and Robert FitzStephen, both sons of the Welsh princess Nesta. Maurice and Robert were promised Wexford town and two adjoining cantreds for their services, while de Clare, also known as Strongbow, was offered Dermot's daughter Aoife in marriage and promised the whole province of Leinster on Dermot's death. Between 1168 and 1171 the Cambro-Normans not only reconquered all of Leinster with Dermot MacMurrough, including Dublin, but invaded the neighboring province of Meath and harried Tighernan O'Rourke's kingdom of Breifne.

Dermot MacMurrough died in May 1171, and Strongbow established himself as lord of Leinster, after crushing a general revolt of the Leinster Irish and Ostmen. Fearing Stongbow's new found power in southeastern Ireland, King Henry II (of England) landed with a large army near Waterford on October 17, 1171. In his Irish campaign Henry received recognition and hostages from the Ostmen (Vikings) of Wexford, who had captured Robert FitzStephen, as well as from many other kings in Ireland. Among those was said to include Dermot McCarthy (Diarmait MacCarthaigh), king of Cork; Donal Mor O'Brien (Domhnall Mor O Briain), king of Limerick; Murchadh O'Carroll (O Cearbhaill), king of Airgialla; Tighearnan O'Rourke (O Ruairc), king of Breifne; and Donn Sleibhe MacDunleavy (MacDuinnshleibhe), king of Ulaid. Henry made a formal grant to Strongbow of Leinster in return for homage, fealty, and the service of 100 knights, reserving to himself the city and kingdom of Dublin and all seaports and fortresses.

Henry granted the kingdom of Meath, from the Shannon to the sea, to his own follower Hugh de Lacy. By 1177 John de Courcy conquered Ulaid in northeastern Ireland. Two Irish kingdoms in Munster, considered to be in rebellion, were speculatively granted away. Parts of Cork went to Robert FitzStephen and Miles de Cogan, who took possession of seven cantreds and exacted tribute from McCarthy for the remaining twenty-four. Limerick went to Philip de Braose and others, who failed to conquer any land at all from O'Brien. Following Strongbow's death in 1176 William Marshall, his son in law, was placed in lordship of Leinster. In 1185 Theobald Walter, Philip of Worcester and William de Burgh were introduced into the northeast portion of O'Brien's kingdom of Limerick (Thomond). In 1189 the kingdom of Airgialla was divided between Gilbert Pipard and Bertram de Verdon following the death of King Murchadh O'Carroll. By 1200 the roots of the Cambro-Norman influence in Ireland had been firmly planted by Henry II and his son and successor, John. What followed was a period of both Norman and Irish provincial lords and kings.

Some of the men claimed to have joined Strongbow and Henry II during the Cambro-Norman invasion of Ireland included Robert FitzStephen, Maurice Fitzgerald, Maurice de Pendergast, Raymond le Gros Fitzgerald de Carew, Hervey de Montmaurice, Philip and Robert and William de Barri, Giraldus Cambrensis, Milo and Richard de Cogan, Hugh de Lacey, Philip de Braose, John de Courcy, Adam de Hereford, Robert le Poer, David and Philip Brenach (Walsh), William FitzAdelm de Burgo, Meyler FitzHenry, Walter de Ridelsford, David and Adam and Henry de la Roche, Redmund FitzHugh, William de Wall, William and Phillipe le Hore, Walter Fitzgerald, Theobald FitzWalter le Boutiller (Butler), Robert de Bermingham, Miles FitzDavid, Roger de Gernon, Philip de Hastings, Gilbert d'Angulo, ...
